SCube was our college mini project. The name represents SSS and stands for Synchronous Sashay Simulator. The aim was to provide an efficient, versatile and generalized platform to ascertain the shortest path or the simplest path connecting two places on a map. Our system uses a method totally different from the conventional graph based approach, and provides better results in real world scenarios. It works in two phases. The creation/pre-procession phase in which an intermediate file called the map file is created from a black and white image of the map. Black represents obstacles and white represents traversable area. Non-traversable white patches on the map are removed through a process called lagoon erasing, and then edge detection is performed to get the data required for the intermediate file. Once the map file is create it can be used any number of times for finding path between two points. To find a path, shortest routes over the intersecting edges are taken and smoothened out using our RDH algorithm.

Turech is a numerically controlled construction toy, and was created for college project presentations. At the heart, the system was a set of DC motors controlled using parallel port through an optocoupler-relay array. At the software side, the program was equipped to manage signals send to the data port. It can translate keyboard inputs, record and replay the signal patterns.

ARMADA stands for Artificial Recognition and Manipulation of Alphabetic Datum. It's the C++ implementation of my handwriting recognition algorithm, MAI-II. Back in 2002-03, when Microsoft's tablet PCs were the hot cakes of the tech world, what attracted me most, were the stylus and the magical recognition of characters written with it. Those made me start a mission to create a system that could recognize handwritten characters in any language. After multiple iterations of various algorithms and prototypes, I accomplished my goal; ARMADA core 2 was created. The software can learn the way you write a character, memorize it and use at a later instance to recognize the same. The best part is that it can learn any language.

P2Tester or picture to text converter a tool to convert an image into a monochrome plain text equivalent. The resultant text file can be opened in any normal text editor. The system uses a set of 16 different characters; each character occupies a different screen space. When a mosaic of characters is made, with each pixel replaced with a character of relative intensity, the illusion of an image is created.

Perspective 3D Engine is my C++ implementation of the perspective projection in engineering graphics. Using the tool one can easily design a 3D wireframe; view perspective projection of the same, and alter the projection parameters. The project was initially started as an educational tool to learn the effect of various parameters on the projection of an object. Later the core of the project was used as a 3D engine in some other programs. It helped in animating objects in all three space dimensions.

As a programmer, my key aim back in those days was to explore beyond the boundaries of conventional programming. As I'm more inclined towards graphics, one key objective was to directly control graphics card for better performance, color and resolution. Hence project SVEGA was started. SVEGA provided TC++ APIs for drawing basic shapes and displaying BMP images in SVGA. 256-colored SVGA was a major achievement above the 16-colored VGA provided by graphics header file.

Swing is my attempt to leverage the sound card for music. It enabled playing uncompressed single-track wave files in TC++, and was a major achievement way beyond the frequency based sound tones supported by the language. The library also supported amplitude based graphical visualization of currently played music.

Tumac stands for The Unlimited Machine. It's programmed to calculate Gregorian calendar for any year you can enter in a fraction of a second. This feat is achieved by computing the required calculations while entering the year. The key innovation is a new math to do basic operations from left to right than the known right to left approach.

Graphics and UX had been always my favorite, and there is nothing better than games to experiment with both. Attached are screenshots from some of my DOS games. They helped me learn programming and also came handy in some TC++ presentations.

My relationship with computers started back in 2002, and Turbo C++ 3.0 was the first language that I had my hands on. Beyond the basics, what attracted me most was the graphics header file that gave pixel level control of everything that was happening on the computer screen. These screen shots are from some programs I wrote for learning.
